Placement of recording sites in the dorsal CA1 area. (A) Representative Nissl-stained section showing two lesions of the tetrode tips in the stratum pyramidale. Scale bar, 1 mm. (B) Coronal brain schematics, extending from AP −2.18 to AP −1.7, indicate the recording positions for the tetrodes. Arbitrary color code identifies the positions belonging to each animal, verified by lesion sites (n = 20).
